How Trees Work for Us – Take a Look!

Many animals, such as birds, squirrels, raccoons and a variety of insects, spend much of their lives in trees. These animals are born in trees, live in trees, raise their young in trees and seldom come down to the ground. Trees provide them shelter from the weather and from enemies, food in the form of fruits, nuts, leaves, bark and roots. Even dead trees provide shelter and food for many insects.

We probably can’t think of anyone who lives in a tree, but many of us live in wooden houses made from trees. Furniture and many other obvious items inside our homes are also made from wood.

However, wood is not the only product that comes from trees. Practically every part of a tree is used to make paper for magazines, newspapers, candy wrappers, and cereal boxes. Sap, the liquid that flows in trees, is used to make maple syrup, chewing gum, crayons, paint, and soap. Dyes and medicines are made from the bark, while leaves and roots provide oils for cosmetics and medicines.

Not to be forgotten are the jobs that trees provide for people – loggers and tree planters, for example. All the products made from trees create many more jobs. Did you ever wonder who makes pencils or chewing gum?

Many types of trees provide food for people too. Apples, pears, peaches and cherries come from trees, as do nuts like walnuts and hazelnuts. Trees make our world a nicer place. Image your neighborhood without trees. Parks and campgrounds would certainly not be the same without trees. We all love the sight of trees.

The quality of our environment – the air, soil and water – depends on the roles trees play. Trees help create rain as they expel moisture into the atmosphere: their roots draw it from the soil and their leaves return it to the air. Trees clean the air we breathe by taking in carbon dioxide through the leaves and then giving off oxygen we need to breathe. If trees didn’t breathe, neither could we. Roots help hold soil in place to prevent erosion which not only saves soil, but also keeps our waterways cleaner. You may have observed that water is usually cleaner where an abundance of trees is. Trees provide shade in summer to help cool our homes, in winter, they block wind to help warm our homes.
